Application filed June 20, 1912. Serial NoJWdfiES.

To all whom it may concern Be it known that I, MIRON REYNoLbs, a citizenof the United States of America, residin at Anderson,--in the coufity ofMadi- "son an State of'lndiana, have invented ,cer-

tain new and. useful Improvements in Fluid- ?ressure Regulators, ofwhich the following is a specification.

Thiscinvention relates to certain new and useful improvements influid-pressure regulators and more particularly to improvements upon myformer Patent #746,879 granted December 15, 1903, the object being toimprove the general construction of valve casing and to provide anoutlet within the casing in order to allow the cover to be removedwithout disturbing the pipe system, whereby the interior'of theregulator can be readily reached.

Another object of my invention is to improve the construction of valvelever and manner of mounting the valve block in order to prevent rotarymovement thereof.

, Another object of my invention is to provide novel means for fasteningthe valve block to the adjusting screw in order to allow a universalmovement thereof so as to form a perfect seat upon the valve seat.

()ther and further objects and advantages of the invention willhehereinafter set forth and the novel features thereof defined by theappended claims.

ln the drawings-4T vertical transverse section through the regulator;the outlet pipe being shown in elevation; Fig. 2, is a detail enlargedview of the,

valve lever and valve block partly in section, showing the manner ofmounting the same;

. and Fig. 3, is asection taken on'the line 33 of Fig. 2, showing theconstruction for preventing rotary movement of the valve.

-'ke numerals of reference refer to like figures in the several figuresof the drawings. In carrying out my improved invention, 1 emplo aregulator casing 1 which is provided with an extended recess portion 2having a suitable inlet opening 3 provided with a valve seat 4. Thecasing is also provided with a drain outlet 5 closed by a plug 6 and avent in which is arranged a vent-pipe 7. A cover 8 is secured on thecasing by any suitable means, and disposed between the casing and coveris a flexible, diaphragm 9' which may be of any 'of the constructionsnow in use, which carries a plate 10 u on its upper surface and abracket 11 upon its unof a valve lever 25, which is provides *igure 1,is a central vided with a vertically threaded bore provided with conicalhead 33. which der surface which is carried by a screw extending throughthe plate 10 and diaphragm 9, as clearly shown in Figrl. The cover isprovided with a central chamber 13 in which is arranged a coil springT-l, which bears at its lower end upon the plate 10 over the screvvl2,and the upper end of the spring is engaged, by an adjusting screw 15threaded into the apertured portion of the chamber 13, all of which issubstantially the same as shown in my former patent.

An inlet pipe is arran ed "l 3 and the extended recs L vided with athreaded hoes L7 gles to the inlet and in which an outlet pi 18 issecurerhextending to the desired po The cover of the casing is providedwith a threaded boss 19 in vertical alinement with the inlet in which isarranged a th"- aded plug 20 whichcan be removed to facilitate theadjusting of the adjusting screw carrying the valve block as will helater dc which allows the valve block to be ad usted withoutremoving thecover.

Arranged over the extent ed r T the casing 1 is a bridge 21 w tamed inproper position tjy the cover in ent, said bridge having depending spa22 carrying a pivot pin 23 on which i ally mounted the enlarged hearmgper. 0

an apertured end 26 pivotally mohnted a pin 27 carried by the or? thehraclres 11, sothat the valve lever will lie rocked as the diaphragmexpands and contra ts. T opposite end of the valve lever 2c is pro whichis mounted an adjusting screw having at its lower end a neck portionsecured within a cylindrical seat 32 formed s 1 z in the valve cox 33,Icy swaging the wall of the block, as shown at 84, whereby the head isheld within the socket in such a manner that a universal movement isobtained so as to allow the block to seat itself upon'thel valve seat lof the inlet and in order to provide means for closing the inlet, I formthe valve block 33 with a circular recess 35 in its bottom, in which isarranged a valve or Washer 3'6, whichco-acts with the seat- 4 so as tocompletely close the same By this construction, the valve block isconnected to the adjusting screw in such a 'manner thatthe same 18 freeto rock'm gilt ansamemanner as disclosed in my former rarer to form aperfect closure for the inst, and at the same time the same can be;ccured in position upon the adjusting screw easily and quickly and insuch a manner that all danger of the same becoming accidentally deta hedis prevented.

in order to provide means for preventing the valve block from rotatingupon the conical head, I cut away the upper portion of the same to forma fiat face 37, which is adapted to co-act with a shoulder 38 formed onthe valve lever in such a manner that prevented moved without disturbingthe pipeline, to

which the regulator is attached. It will also be seen that I have proided means for,

reaching the interior of the regulator by simply removing a plug screw1n order to adjust the adjusting screw carrying the valve block.

I claim:

1. In a fluid-pressure regulator, the combination with a valve operatinglever, of an adj usting screw carried by said lever, a valve blockcarried by said screw and having universal movement thereon, said blockbeing provided with a fiat face and a shoulder formed on said valvelever co-acting with the fiat face of the valve block for preventingrotary movement thereof.

2. A fluid-pressure regulator having a pivotally mounted valve leverprovided with a threaded bore, an adjusting screw mounted in said borehaving a neck at-its lower end terminating in a conical head, a valveblock provided with a socket to receive said head and secured thereon byswaging the head of said socket into the neck of said screw, said valveblock being provided with a fiat face, and a shoulder formed on thevalve lever oo-acting with said face for preventing rotary movement ofsaid block in respect to said screw.

3. A gas governor comprising a' diaphragm, a'lever pivoted to saiddiaphragm, a pivot for said lever, a screw adjustably inserted downwardthrough one end portion of said lever, a valve seat, a valve hung on thelower end of said screw, having a rocking and rotative connectiontherewith, adapted to enga e said seat, and means independent of saiscrew, for engaging the lower portion of said lever, disposed on theside of thevalve toward the pivot, to hold the valve against rotation,but permitting adjustment of said screw to change the op-- erativeposition of said valve on said lever.

In testimony whereof athx my signature in presence of two witnesses.
